Turns pro in 1967 and goes along this route. How' do the fights go? Challenged welter weight champ, Jose Napoles in 1969? Challenged Carmelo Bossi for light middle weight title in 1971? Back to welter weight in 1972, challenging Hedgemon Lewis? Retires. Comeback in 1974. Challengers Rodrigo Valdez for WBC Middle weight title? Retires again. Comeback in 1976 to challenge John Conteh for WBC Light heavyweight strap? Drops back Light middle in 1977 and fights Rocky Mattoli for his belt? Retires then makes one final come back in 1981 to to on a little known fighter called Ayub Kalule for the WBA light middle weight title!
I'd say he loses to Napoles and Conteh, although Leonard could possibly win on cuts vs Napoles. I don't know enough about Valdez to comment. And finally I think he beats the rest.
He finds himself too much in Ali's shadow to become as iconic among normal boxing fans. As a result, Classic forumites like him a lot more.
If he doesn't offer an immediate rematch to Napoles within ten days, he will be derided in Letters To the Editor in The Ring Magazine by redrooster's dad.
